Present-day electric cars aren\u2019t just about the speed & acceleration. They are smart co-pilots which take you from one place to another safely. These cars are powered by a system known as ADAS. In this blog<\/span>,<\/span> EVJoints<\/span><\/a> brings you the hows & whys of ADAS and a lot more:<\/span><\/p>\n

What is ADAS?<\/b><\/p>\n

ADAS or Advanced Driver Assistance System is the \u2018brain & senses\u2019 that turn a regular electric car into a much smarter & safer machine. It uses a combination of sensors, cameras, computers & software to perceive the environment around the vehicle and either assist the driver or take partial control when needed.<\/span><\/p>\n

What types of sensors does ADAS use?<\/b><\/p>\n

ADAS can use multiple types of sensors, but the two most common are cameras & radar. Many cars combine both.<\/span><\/p>\n

How does camera-based ADAS work?<\/b><\/p>\n

Camera-based ADAS <\/span>looks at the world through cameras and tries to understand the scene exactly the way an attentive driver would. Camera-based ADAS recognizes shapes, colours & text. Its performance can drop during rains, fog & low light. Common camera-based ADAS features include: lane keep assist, traffic sign recognition, pedestrian detection, driver drowsiness alert, automatic headlight control, etc.<\/span><\/p>\n

How does radar-based ADAS work?<\/b>\u00a0<\/span><\/p>\n

Radar-based ADAS relies on radar sensors to make measurements around the vehicle. It works in all weather & lighting conditions. Common radar-based ADAS features include: adaptive cruise control, forward collision warning, blind spot detection, automatic emergency braking, etc.\u00a0<\/span><\/p>\n

What about a combination of camera-based & radar-based ADAS?<\/b><\/p>\n

Sensor fusion in ADAS (combining camera-based & radar-based systems) has become standard in many premium electric cars sold in India. This fusion enables Level 2 ADAS features like Adaptive Cruise Control (ACC), Lane Keep Assist (LKA), Autonomous Emergency Braking (AEB) & Blind-Spot Monitoring, thereby improving safety on Indian roads.<\/span><\/p>\n

Most electric cars in India use a combination setup for ADAS (cameras + radar).<\/span><\/p>\n

Why electric cars come with better ADAS systems than petrol\/diesel cars?<\/b><\/p>\n

Electric cars often appear to have more advanced or more capable ADAS than fuel-powered cars. This is because of:<\/span><\/p>\n
